SPECICATION forming part of Letters Patent No. 339,610, dated April 6,1886.

I Application tiled January 4, 1886. Serial No. 187,550. (No model.)

To (LZZ whom it may concern:

Be it known that I, Grenen W. WRIGHT, of Carterville, in the county of Jasper and State of Missouri, have invented a new and useful Improvement in Flows, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof,u in which- Figure lis a plan view. Fig. 2 is a side elevation. Fig. 3 is an inverted plan view of the landside and mold-board. Fig. 4 is an inside view of the mold-board.

Similar letters of reference indicate correspending parts in the different figures of the drawings.

The object of my invention is to facilitate the turning of adhesive soil, to reduce the power required to draw the plow forward, and to avoid the necessity of maintaining a high polish on the face of the plowshare, moldboard, and landside.

My invention consists in the combination, with the mold-board and landside of a plow, of means for maintaining them in aheated condition.

In my drawings I have shown means for carrying out my invention, consisting in the application to the back of the mold-board and landside of the plow of a steanrjaclret supplied with steam by a boiler carried on the frame of the plow, the steam-jackets of the mold-board and landside being provided with means for removing the water of condensation. |lhe beam A of the plow is formed of two parallel bars of iron separated at the forward end by a plate, ft, carrying the bearing b of the axle e of the caster-wheel d, the caster-wheel d being journaled on the end of the crank-axle c, pivoted to the bearing b. The axle c is provided with a clevis, e, to which horses are attached in the usual way. The rear ends of the bars forming the beam Aaresecured to opposite sides of an arm, B, which extends downward, and is bent out ward laterally at right angles to receive the wheel C, which rolls on the bottom of thefurrow.

To an arm, D, secured between the barsl of the beam A, near the rear end thereof, and extending downward and forward, is pivoted the landside E of the plow F, and the standard G of the plow extends upward between board the bars of the beam A. An annular frame, H, is secured to the side of the beam A at a point opposite the plow F, and is stayed by a brace, l, which is secured to the outer sideof the annular frame H, and also to the forward end of the beam A. The annular frame H is also further supported by an arm, J, (shown in dotted lines in Fig. 1,) which projects from 6o the side of the beam A at right angles, and is bent forward at right angles at its outer end and attached to the annular frame H. y

To the arm J are secured the boxes f of the rear axle, K, which projects beyond the outer 6 5 box and beyond the annular frame H, and carries at its outer end a wheel, L. The end of the axle K nearest the beam A supports a lever, M, placed loosely on the axle, and pro vided with a bolt, g, which engages a curved 7o notched bar, h, secured to theinner side of the beam A, the bolt g serving to hold the lever M in any desired position.

To the boss of the lever M is secured a toothed sector, i, and to the end of theaxle K,

outside of the lever M, is secured a lever, N, provided with a bolt, j, which engages the toothed sector t', and holds the axle K in any desired position relative to the lever M. The

lever M is connected by a rod, O, with the np- 8o per end of the standard G of the plow F by pivotal connections, so thatv by moving the lever M the share of the plow may be elevated or depressed. Vhen the boltY j of the lever N is in engagement with the toothed sector i,

the movement of the lever M simultaneously tilts the plow and turns the axle K, so that the standard of the plow is maintained in an approximately vertical plane. A steanrboiler, P, of any approved construction, is sup- 9o baclr, R, and the landside S is provided with a steam jacket or back, T. The lower part of the steam-jacket Roi the mold-board and the rear end of the jacket T of the landside are shoulder formed at the lower Q is provided with a steam jacket or 10o connected with each other and with the valve o by the pipe p', which forms a way of escape for the water of condensation from the jackets RT, and also acts as a brace between the landside and mold-board. The jackets R T communicate with each other at the lower part of the plow, andthe top of the jacket R is connected by a flexible pipe, q, and through the valve fr with the steam-room of the boiler, and the bottom of the jacket R of the moldboard is connected by the pipe s, flexible pipe t, and pipe u with the top of the water-reservoir U, the pipe u being provided with a valve, o. The water-reservoir communicates with the steam-room of the boiler through the valve w, and with the waterspace of the boiler through the valve x, and the top of the waterreservoir U is provided with an air-cock, y. Steam is generated in the boiler P, and is permitted to pass to the jackets of the moldboard andlandside through the valve rand pipe q, and the water of condensation is allowed to escape from jackets of the landside and moldboard through the pipe p and valve o, or it may be returned to the boiler by opening the air-cock y in the top of the water-reservoir U and opening the valve v in the pipe a, the valves 'w being closed,when the steam-pressure in the jackets will force the water contained in the lower portion thereof through the pipes s t u to the water-reservoirU. The feeding of the boiler P is effected by closing the air-cock y and opening the "alves w x more or less, thus equalizing the pressure in the water-reservoir, and permitting the water t0 ow by its own gravity from the reservoir through the valve x into the water-space of the boiler. Should it be found undesirable to maintain the boiler-pressure in the jackets R T during the time of supplying the boiler with water, the valve o in the pipe u may be closed. i

I have described a means of heating the mold-board and landside of a plow by the use of steam; but the same effects may be produced by heating it in any other Way; but I prefer steam as being the most convenient and not liable to injure the temper of the moldboard or landside.

By heating the mold-board and landside of the plow in the manner described a thin stratum of steam is formed of the'moisture of the soil on the surface of themoldboard,which separates the soil from the mold-board and landside, causing itto slide over the plow and to turn with greatly-diminished friction, so that less power is required to draw the lplow forward, and the polish of the mold-board and landside will require less care and attention. When the soil contains so little moisture as to render it impossible to generate enough steam on the face of the mold-board to cause the soil to slide freely over the mold-board, I provide in the lower edge of the mold-board or landside, or both, one or more small apertures, a', communicating with the steam-jacket and furnishing a small amount of steam to the rubbing faces of the plow.

I am aware that the mold-boards of plows have been heated to cause the soil to slide over them. Therefore I do not broadly claim the heating of mold-boards.

, Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. I n a plow, a mold-board provided with a steam -jacket upon the back thereof and means for supplying steam to the jacket and removing the water of condensation therefrom, substantially as herein specified.

2. The combination, with the mold-board or landside of a plow having apertures a, of a steam-jacket placed on the back of the moldboard or landside for supplying a stratum of steam to the face thereof through the holes a', substantially as described.

.3. In a plow, a mold-board and landside, each provided with a steam-jacket on the back thereof', and means for supplying steam to the jackets and removing the water of condensation therefrom, substantially as herein specified.

5. In a plow, the combination, with the mold-board Q, provided with the steam-jacket R, and the landside S, provided'with the steam-jacket T, of the boiler P, carried by the frame of the plow, and pipe-connections between the steam-room of the boiler and the steam-jackets, substantially as herein shown and described.

6. In a plow, the combination,- with the mold-board Q, provided with the jacketR, and the landsideS, provided with the jacket T, of the pipe p, the boiler P, the water-reservoir U, provided with the air-cocky, the valves w x, and the flexible pipe-connections connecting the boiler and the water-reservoir U with the jackets RT, substantially as herein shown and described. i
